I really like the mighty mouse (not the side buttons. Why Apple can't just accept another standard that works really well and get on with the business of selling computers I don' know), but I hope it's better than other otical mice. I've got a BT Mac mice and tried the Apple wireless optical and frankly, they both suck a lot of battery and don't respond nearly as well as their PC equivalents do.

Frankly Apple mic have always been their weakest feature. Then again Apple has never been willing to change just because a better idea comes along.

I get 24 (a box of 6 four-packs) of Energizer Industrial AA batteries for less than $10. A pair lasts me about 6 weeks in the mouse, so 18 of these should last me a year, with 12 left over for the keyboard. That's probably about right.

I actually like the scrollball, I know I'm probably in the minority here but there it is. I'm with you on the side buttons though, can't stand them. It just feels so un-natural to me. I have heard that bluetooth mice in general are quite un responsive, that is really the only thing which has stopped me from buying one! is it true? cos I would really like a decent and reliable wireless mouse!

I don't like the scrollball but it is the easiest to use when navigating sideways on wide pages. Tried a tlit wheel and it kept centre clicking every time.

The side buttons are simply POINTLESS. Why have two that can only be harnessed to a single function? My Logitech MX700 knocks spots of any Apple mouse. If the MM buttons were usable for forward/back browsing it would be so much better.

I've just acquired a cheap BT mouse and overall it's OK but when you first move it nothing happens and then it suddenly rushes across the screen to catch up. Reducing the speed and acceleration don't seem to do much to alleviate the turbocharged speed it develops when the pointer finally seems to move. I certainly wouldn't waste money on an Apple BT MM.

It also tends to lose the connection a lot even though it's a foot away from the iMac though that may be a battery thing.

For $10/year (or even twice that), I can't see messing with rechargables.

I'm left handed, so you can probably guess how I feel about all those 'ergonomic' mice!
Seriously, it's annoying because most of the mice people recomend are these shaped ones and I simply can't use them!
Which is why I'm giving some serious thought to the MM, Can anyone give me an idea of battery life on the original apple bt mouse, just for comparison's sake?_________________mac mini coreduo 1.66ghz. 1.25gb 60gb HD
